I posted a few weeks ago a couple of articles which may, or may not be of any use to some of you guys.
I've always been an MOA shooter, so getting my head around Millirads was somewhat of a headache, however after I "got it" i decided to try and word it in an easier to understand article than those I had been reading.
To understand what a Milliradian is (Shortened to Mil) then : http://blog.stegough.com/understanding-milliradians-mil-milrad/
Once you've got that an want to see how Mils relate to Mil-Dot Scopes then : http://blog.stegough.com/understanding-the-mil-dot-reticle/
Hopefully this helps someone. I dare say a lot of you guys that shoot all the time will already know it, but certainly one for the novices, and those that shoot MOA but want to know more.
